Water Level

Water Level and Current Velocity

Tidal Constituent

The CMS follows the National Oceanographic and Atmospheric Administration (NOAA) National Ocean Service (NOS) convention for astronomical water level predictions. The water level predictions are based on a harmonic equation with several arguments

  η=∑i=1NfiAicos⁡(ωit+V0i+ui−κi) (1)


Symbol Description
A Constituent amplitude
f Constituent nodal factor
V0 Constituent equilibrium argument
u Constituent equilibrium argument
κ Constituent phase or epoch
